Patented Jam, 1914..

Be it known that I,"W11.Lmn D. Fon- I a citizen of the United States,residing.at Youngstown, in the county of Mahnoining and State of Ohio,have nvented new and ansefuil improvements in Forged Car-Truck SideFrames, of which "the following is a specification.

My invention relates to forged car truck m'de frames. The principalobject of my invention is to provide a car 'hmk side frame made from twosimrfle structural of rolled, forged or pressed metal.

My invention consists of an-car t-ruck side frame made from twostructurai shapes, each a singlerpiece of roiled, forged or pressedmetal, the first comprising a compression member and a tension memberintegral with each'other'; the second a truss member so,v

shaped as to provide a bolster opening and to be attached to the first;the distribution ofanetal in all of the members of the frame andtheirparts is one of the novel and essent-ial features of my invention.

In the accompanying drawings, Figure l is a side View of the car truckside frame;

- Fig. 2 is .a' top planview of 1; Fig. 3

is an end View of the structural shape from which the frameis made; Fig.4 is aside view of said shape, with dotted lines showing where the sameis sheared and a horizontal iine indicating the top surface of the webof said shape; Fig. 5 is aside view of said shape, :sli tt'ed, bent andexpanded; Fig.

6 is a top plan view of Fig. 5; Fig. 7 is a,

7 section of Fig. 1-on iine A-A; Fig. '8 is a section of Fig. 1 on line3 -13; Fig. 9 is a section of Fig. 1 on line 'O'G; Fig. 10 is a sideView of the tram member ofthe frame; Fig. 11 is an end View of Fig. 10.

Like figures of reference refer 1:0 like parts throughout.

In Figs. '3' and 4, 1 is a structural metal shape having a web 2;flanges .3, 3, and wings 4, 4. The flanges 3, 3, are at the outer edgesof the web 21nd extend therefrom substantially at right angles. Wings 4,4, extend substantially at right angles to the web in a directionopposite to flanges 3, 3, and are inset from the edges so that theirouter surfaces are. substantially in the same. plane as theinner-surfaces of flanges 3, 3. Flanges 3, 3, are sheared alongundulating line 5.

Wings are sheared between points and 7 mam @4 along dotted line 8, andthe underside of flanges 3, 3. The web 2 is sjlitted by two parallelslits substantially along dotted lines 9, 9, Flg. 3, said slitsextending from point 10 to point 11, Fig. 5; that is to say, the. web 2is divided into three sections, consisting of two ends comprising thatpart of the web 2, having journal box bolt holes 2*, between points 1'0and 11 andthe respective ends of said web, and that portion of the webbetween points 10 and 11, Figs. 5 and '6;

When the structural shape 1 has been slitted, as hereinbefore described'bysuitable apparatus, the flanges 3, 3, are bent and formed by pressingorforging so as to have the curves 12, 12, along their outer edges andso that their inner edges shall besubstantlally in lines 13, 14; and 15of the hexegonal opening 1- 6 of the frame, and the web and its wingsare so formed and stretched by suitable operations and apparatus as totake the shape shown in 5 the outside edges of the wings 4, 4, nowconstituting. the V-shaped flanges of the web and the'top surfaces ofthe web having substantially the lines 17, 138 and 1 9 lying in theremaining three sides of the hexagonal opening 16.

The compression member of the frame is. constituted of the flanges 3, 3,bent so as to.

have the curves 12, 12, and the sides 13,14 and 15. The tension memberof the frame is constituted by that portion of the web betweenpoints 10and 11, with its top side being substantaaily on the lines 17, 18 and19, and said wings 4, 4:, now constitute-the flanges of the tensionmember, being of the shape shown inside view in Fig. 5. It will be notedthat "the greatest depth .of metal verticai ly in the compression memberis between points 1'01-0 and 11-11, along the dotted lines BO, andthat'the greatest depth of rnetal in the tension member is betweenpoints 21-21, along dottedlines 22. The ends of the frame are thoseportions thereof as are between point 10 and the end of 1, at

one end thereof, and point llyan'd the other end of 1.

In Figs. 10, 23 is the truss member of the frame. This member \ispreferably made out of a structural shape shown in solid lines anddotted lines 25', in Fig. 11'; said structural shape forming trussmember 23 has a web '25 and two flanges 26, 26, intermediate the edgesof said web, which are parallel t-o eachother. Web 25 is sheared so asto have the shape shown in Figs. 1,. 7, 10 and' 11, and so that itsflanges 26 may be inserted between the flanges of the compression member3, 3, as shown at the top of Fig. 7, and

to be wider at" the bottom than at the top. When said truss member hasbeen inserted inside of said flanges 3, 3, and the tension member of theframe has been J inserted within its flanges 26, 26, it is riveted inthis position in a suitable way.

It will be noted that the web 25 of the truss member bridges for thelength of the flange 'of the truss member, the space between flanges 3,3-, forming the compression member of the frame and reinforces the webof the tension member at the bottom of the frame. The truss member'maybe welded at line 27 27, .or the ends thereof may be butted together atsaid line. I What I claim as my invention is: 1.
